The juicer cutter provided by the embodiment of the invention can be used for scraping pulp inside fruits to prepare juice, and comprises a rotating piece, an elastic blade and a radial abduction mechanism.
The radially outward extending mechanism includes a plurality of members in rotational or movable connection therebetween, a portion of the plurality of members being movably connected to the rotary member. The relative positional relationship between the members of the plurality of members may change upon relative movement therebetween, and in a reasonable arrangement, the plurality of members may be partially or fully retracted within/around the rotating member or deployed radially of the rotating member upon actuation of one of the members relative to the other.
The rotary member has a predetermined length; the elastic blade is arranged along the length direction of the rotating piece; the radial abduction mechanism is arranged between the rotating piece and the elastic blade and is connected with the rotating piece and the elastic blade, and the radial abduction mechanism can drive the elastic blade to be far away from and close to the rotating piece along the radial direction of the rotating piece. The resilient blade may also be brought into close proximity with the rotating member when the radially outward extending mechanism is retracted to allow the juicer cutter to have a smaller radial dimension for insertion into the fruit. After the juice extractor cutter is inserted into the fruit, the rotating piece can be driven to rotate around the rotating shaft of the juice extractor cutter, and meanwhile, the radial abduction mechanism and the elastic blade are driven to rotate. When the juice extractor cutter rotates, the radial abduction mechanism can be driven to act, so that the elastic blade is gradually far away from the rotating piece, and the purpose that the elastic blade scrapes pulp from the center of the fruit to the peel is realized. In the above process, both ends of the elastic blade are bent by resistance of the pulp and/or the peel, the elastic blade has a certain radian, can be attached to the inner surface of the peel, and can fully scrape pulp.

The juice extractor cutter 100 includes a rotary member 110, a slide bar 120, a first rocker arm 130, a second rocker arm 140, a first link 150, a second link 160, and two resilient blades 190. The sliding rod 120 is capable of sliding along the rotating member 110, the first rocker arm 130 is hinged to the rotating member 110, and the first link 150 connects the sliding rod 120 and the first rocker arm 130, such that the sliding rod 120, the first rocker arm 130 and the first link 150 form a rocker slider mechanism, i.e. a set of radially outwardly extending mechanisms. The slide bar 120, the second rocker arm 140 and the second link 160 form another set of rocker slider mechanisms, i.e. another set of radially outwardly extending mechanisms. One elastic blade 190 is disposed along the length direction of the rotary member 110 with one end connected to the bottom end of the rotary member 110, and one face of the elastic blade 190 perpendicular to the thickness direction thereof faces the rotary member 110. The other elastic blade 190 is connected to the rotating member 110 in the same manner and is symmetrical with the one elastic blade 190 with respect to the rotating member 110. In this embodiment, the elastic blade 190 is hinged to the rotating member 110, and the hinge axis is parallel to the width direction of the elastic blade 190.
The rotating member 110 is a rotating shaft, and a long groove 111 is provided in a part of the shaft body of the rotating shaft along the length direction, and the long groove 111 penetrates the rotating shaft from the radial direction. One end of the rotating shaft is provided with an axial central hole which is communicated with the long groove 111; the other end of the rotating shaft is also provided with a radial pin hole, and the direction of the pin hole is parallel to the width direction of the long groove 111, namely, the pin hole is a radial hole.
The sliding rod 120 is a cylindrical rod, and one end of the sliding rod is provided with a pin hole which is radially penetrated. The slide bar 120 is disposed in the central hole of the rotating member 110, and one end of the slide bar 120 having a pin hole may extend into the long groove 111 of the rotating member 110, and the other end may extend out of the central hole of the rotating member 110. The slide bar 120 can reciprocally slide in the central bore of the rotary member 110.
The first rocker arm 130 is a rod-like structure. The first rocker arm 130 is provided with pin holes at both ends and the middle, and axes of the three pin holes are parallel. 130 are disposed in the elongated slot of the rotary member 110 at one end, and the pin holes at the end are disposed coaxially with the pin holes on the rotary member 110 and are connected by pin shafts to form a hinge connection. The first rocker arm 130 may rotate on the rotating member 110, and the other end thereof may be far from or near the rotating member 110 at one side of the rotating member 110 when rotating. In this embodiment, the free end of the first rocker arm 130 is further provided with a rotatable roller 199, and the axis of the roller 199 is parallel to the pin hole axis of the first rocker arm 130. In an alternative embodiment, the edges of the circumferential surface of the roller 199 (roller end surface edges) are also provided with flanges, and the distance between the flanges may be equal to or greater than the width of the resilient blade 190.
The first link 150 has a bar-shaped structure, and both ends thereof are provided with pin holes for hinge connection, the two pin holes being parallel. One end of the first link 150 is hinged to one end of the slide bar 120, and the other end of the first link 150 is hinged to a pin hole in the middle of the first swing arm 130. The sliding rod 120, the first rocker arm 130 and the first connecting rod 150 form a rocker arm sliding block mechanism, when the sliding rod 120 slides reciprocally on the rotating member 110, the first rocker arm 130 can be driven to swing around the hinge on the rotating member 110, and the first rocker arm 130 and the first connecting rod 150 can be folded into the long groove of the rotating member 110.
The elastic blade 190 is a long blade, and is elastically bent in the thickness direction thereof, and the edge in the width direction thereof scrapes pulp. The side of the end portion of the elastic blade 190 facing away from the rotary 110 is a cambered surface 191.
One end of one of the elastic blades 190 is hinged to the bottom end of the rotating member 110 and is on the same plane as the first swing arm 130, i.e., the circumferential surface of the roller 199 at the other end of the first swing arm 130 can abut against one surface of the elastic blade 190 facing the rotating member 110 when the first swing arm 130 rotates on the rotating member 110, pushing the part of the elastic blade 190 not connected to the rotating member 110 away from the rotating member 110 in the radial direction of the rotating member 110.
The second swing arm 140 has the same structure as the first swing arm 130, and one end is hinged to a pin hole at the end of the rotating member 110 and is symmetrical to the first swing arm 130 with respect to the rotating member 110. The free end of the second rocker arm 140 is also provided with a roller 199.
The second link 160 has the same structure as the first link 150. The two ends of the second link 160 are respectively hinged to the pin hole in the middle of the second swing arm 140 and the pin hole at the end of the slide bar 120. The second link 160 and the first link 150 are symmetrical with respect to the rotary 110.
One end of the other elastic blade 190 is hinged to the bottom end of the rotating member 110 and is on the same plane as the second swing arm 140, i.e., the circumferential surface of the roller 199 at the other end of the second swing arm 140 can abut against the surface of the elastic blade 190 facing the rotating member 110 when the second swing arm 140 rotates on the rotating member 110, pushing the part of the elastic blade 190 not connected to the rotating member 110 away from the rotating member 110 in the radial direction of the rotating member 110.
When in use, the sliding rod 120 slides towards the outside of the central hole of the rotating member 110, at this time, the first link 150 and the second link 160 respectively drive the first rocker arm 130 and the second rocker arm 140 to approach the rotating member 110 at the same time, and finally the first rocker arm 130, the second rocker arm 140, the first link 150 and the second link 160 are folded into the long groove 111 of the rotating member 110, and the two elastic blades 190 are rotated to be positioned in the long groove 111 or close to/close to the rotating member 110. At this time, the juice extractor cutter 100 has a small radial dimension, and the juice extractor cutter 100 can be integrally inserted into the interior of a fruit such as orange, and the orange or the juice extractor cutter 100 is rotated, thereby generating a relative rotation between the elastic blade 190 and the fruit. During the rotation, the sliding rod 120 is driven to insert into the central hole of the rotating member 110, so that the elastic blade 190 is gradually pushed away from the rotating member 110 by the first rocker arm 130 and the second rocker arm 140 in the process of rotating around the center line of the fruit, the free end of the elastic blade 190 is bent into an arc shape under the action of the pulp and/or the pericarp, the scraping of the pulp layer by layer is realized, and the pulp in the fruit is scraped into juice until the elastic blade 190 is tightly attached to the inner surface of the orange peel.
During the process of folding the first rocker arm 130 and the second rocker arm 140 into the long groove 111, the elastic blade 190 may gradually return from the arc shape to the original straight shape due to elasticity.
The end of the elastic blade 190 which is not hinged to the rotating member 110 is a free end, so that the elastic blade 190 is pressed by the pulp and the peel in the process of approaching the orange peel, so that the elastic blade 190 is curved in an arc shape, namely, the arc fitting with the inner surface of the fruit peel can be formed, and the pulp is scraped more fully.
The side of the end portion of the elastic blade 190 facing away from the rotary 110 is a cambered surface 191. In use, the end of the resilient blade 190 has a relatively high pressure between the side facing away from the rotator 110 and the pulp or peel, and when this portion is formed as a curved surface, the end is free of sharp corners, thereby reducing the damage to the peel by the blade.
In some alternative embodiments, the end portions of the resilient blades 190 are cambered surfaces on sides perpendicular to the width direction and facing away from the rotating member 110. In some alternative embodiments, the tips of the flexible blades 190 have a rounded curved surface, i.e., the tips of the flexible blades 190 are rounded, to further reduce shaving of the peel. Of course, other configurations for removing sharp corners from the distal end of the resilient blade 190 may also mitigate shaving of the peel, such as a chamfer or rounded corner configuration.
The first swing arm 130, the second swing arm 140, the first link 150 and the second link 160 are positioned at a side of the elastic blade 190 facing the rotating member 110, and thus do not contact the untapered pulp portion, and do not generate a large resistance to the rotation of the juice extractor cutter 100 or the fruit. When the fruit is fixed or driven to rotate, the fruit needs to be clamped, so that a clamping object (or the hand of an operator) and the surface of the fruit peel generate enough static friction force. When the resistance between the juice extractor cutter 100 and the inside of the fruit is small, the need for static friction between the grip (or the hand of the operator) and the surface of the fruit skin is also reduced, so that the fruit surface does not need to be applied with too much pressure, the fruit is prevented from being deformed, and the fruit juice is prevented from overflowing or the surface of the fruit skin is prevented from being scraped and damaged by the elastic blade 190.
The elastic blade 190 is hinged to the rotating member 110, and when the first rocker arm 130 or the second rocker arm 140 pushes the elastic blade 190 away from the rotating member 110, the hinged end of the elastic blade 190 can freely rotate, so that deformation of the elastic blade 190 is not hindered. In alternative embodiments, the resilient blade 190 may also be a fixed connection with the rotating member 110.
In the above embodiment, one end of the elastic blade 190 is connected to the rotating member 110, and the other end is in a completely free state. In some alternative embodiments, the other end of the resilient blade 190 may also be arranged to be slidable in the axial direction of the rotary 110. Specifically, a guide structure (e.g., a ring) having a hole/groove for passing the elastic blade 190 may be provided on the rotating member 110 at a position corresponding to the free end of the elastic blade 190, and the opening direction of the hole/groove may be along the axial direction of the rotating member 110, and the free end of the elastic blade 190 may pass through and slide in the hole/groove of the guide structure. The opening of the hole/slot may also be flared to mitigate the obstruction of outward expansion of the resilient blade 190. In other alternative embodiments, the guide structure may be configured to rotate on the rotating member 110, and the axial direction of rotation may be along the radial direction of the rotating member 110 or parallel to the radial direction of the rotating member 110, and the opening direction of the hole/groove of the guide structure may be changed to accommodate the deformation of the elastic blade 190.
Referring to fig. 4, fig. 4 is a schematic cross-sectional view of an elastomeric blade provided in accordance with an alternative embodiment of the present invention. The surface 192a is a side of the elastic blade facing the rotary member 110, the surface 193a is a side of the elastic blade facing away from the rotary member 110, and the side 194a is a side facing the elastic blade in the width direction. The side 194a is at an acute angle to the surface 193a, which are both faces of the blade. In this alternative embodiment, rib 195a is provided on surface 193a to protrude from the surface thereof, and rib 195a extends in a direction consistent with the length direction of resilient blade 190. Rib 195a has a cylindrical or conical surface, i.e., the rib has an arcuate surface in cross-section. The ribs 195a can reduce the compression of the surface 193a of the elastic blade and the inner surface of the fruit peel, thereby preventing the cutting edge of the elastic blade 190 from cutting into the fruit peel too much and reducing the scraping of the fruit peel; in addition, the rib 195a has a rounded surface, so that the rotation resistance of the juice extractor cutter is not significantly increased; meanwhile, the smooth surface of the rib 195a can squeeze the pulp attached to the inner surface of the fruit peel to extract the juice; in addition, ribs 195a increase the torsional stiffness of the blade and prevent torsional deformation of the resilient blade.
Referring to fig. 5, fig. 5 is a schematic cross-sectional view of an elastomeric blade in accordance with another alternative embodiment of the invention; the method comprises the steps of carrying out a first treatment on the surface of the In this alternative embodiment, surface 192b is the side facing the rotary member 110, surface 193b is the side facing away from the rotary member 110, and side 194b is the side facing the width direction of the resilient blade. The side 194b is at an acute angle to the surface 193b, i.e., both are two faces of the blade. The surface 193b is an arc surface as a whole, that is, the surface of the side of the elastic blade 190 facing away from the rotating member 110 is an arc shape in the cross section of the elastic blade 190, so that excessive shaving of peel by the edge of the elastic blade 190 can be prevented, and torsional rigidity of the blade can be increased, and torsional deformation can be prevented.
Referring to fig. 6, fig. 6 is a schematic view of the structure of an elastic blade in an alternative embodiment according to the present invention, the view direction is along the thickness direction of the resilient blade 190. In this alternative embodiment, the width of the portion of the resilient blade 190 for connection with the rocker arm is greater than the width of the end portions thereof, decreasing from the middle to both ends. The arrangement can lighten the torque of the two ends of the elastic blade to the middle part, which is equivalent to increasing the torsional rigidity of the elastic blade and reducing the possibility of torsion of the elastic blade.
Referring to fig. 7 and 8, fig. 7 is a schematic structural view of a juice extractor cutter 200 according to another embodiment of the present invention, and fig. 8 is a schematic structural view of a stopper in fig. 7. The two-dot chain line coil in fig. 7 is used to illustrate the peel contour of the fruit. The juice extractor cutter 200 includes a rotary member 210, a slide bar 220, a first rocker arm 230, a second rocker arm 240, a first link 250, a second link 260, and two resilient blades 290.
The juice extractor cutter 200 in this embodiment has substantially the same structure as the juice extractor cutter 100, except that: the juice extractor cutter 200 further comprises a stop 10: the length of the elastic blade 290 is greater than that of the elastic blade 190, and one end of the elastic blade 290 is fixed to the bottom end of the rotating member 210: first rocker arm 230 and second rocker arm 240 the free end of (a) is not provided with rollers.
The stopper 10 includes a ring body 11, a stopper portion 12, and a stopper portion 13. In this embodiment, the limiting portion 12 and the limiting portion 13 have a cylindrical structure, and are in a central symmetry relationship with respect to the center of the ring body 11. The ring body 11 has a center hole, and the stopper 12 and the stopper 13 protrude from the ring body 11 in the radial direction.
The stopper 10 is mounted at one end of the rotary member 210 (the end of the central hole that opens) through its central hole, and the stopper 10 is capable of sliding in the axial direction of the rotary member 210. When the stopper 10 is mounted on the rotating member 210, the limiting portion 12 is located on a side of one elastic blade 290 facing away from the rotating member 210, and a surface of one end of the elastic blade 290 facing away from the rotating member 210 abuts against the limiting portion 12. The limiting part 13 is positioned on one side of the other elastic blade 290 facing away from the rotating member 210, and one side of one end of the elastic blade 290 facing away from the rotating member 210 abuts against the limiting part 13.
When the elastic blades 290 are driven by the free ends of the first rocker arm 230 and the second rocker arm 240 to be far away from the rotating member 210, the limiting portions 12 and 13 can limit one ends of the two elastic blades 290 respectively, but do not limit the sliding of the surfaces of the two elastic blades 290 relative to the limiting portions 12, so that the ends of the elastic blades 290 bend towards the center of the fruit, and excessive scraping of the peel parts at the fruit inserting openings by the elastic blades 290 can be avoided. The curvature center of the elastic blade 290 after bending is on the side of the elastic blade 290 facing the rotating member 210, and the curved arc is closer to the shape of the fruit peel, so that the fruit pulp is scraped more fully.
Referring to fig. 9 and 10, fig. 9 is a schematic structural view of a juice extractor cutter according to another embodiment of the present invention, and fig. 10 is a schematic structural view of a stopper in fig. 9.
The juice extractor cutter 600 in this embodiment has substantially the same structure as the juice extractor cutter 100, except that the juice extractor cutter 600 further includes a stopper 20.
The stopper 20 includes a ring body 181b, two holes 23, and two stopper portions 22. The ring body 181b is a disk-shaped ring structure, the center of the disk is provided with a center hole, and the disk body is provided with two holes 23 penetrating in the thickness direction. One side wall of the hole 23 forms a stopper 22. The two limit parts 22 are in a central symmetrical relationship with respect to the center of the central hole of the stopper 20.
The central hole of the stop block 20 is sleeved on the slide bar 620 and can axially slide on the slide bar 620. In alternative embodiments, the stop 20 may also fit over the swivel 610. One end of one resilient blade 690 passes through one hole 23 in the stopper 20 and one end of the other resilient blade 690 passes through the other hole 23 in the stopper 20. When the resilient blade 690 moves away from the rotating member 610, the stopper 20 has a stopper portion 22 that restricts the resilient blade 690 from moving away from the rotating member 610, but does not restrict the sliding of the surface thereof with respect to the stopper portion 22, thereby bending the resilient blade 690. The above arrangement can alleviate excessive scraping of the peel at the knife insertion opening on the fruit by the resilient blade 690.
Referring to fig. 11 and 12, fig. 11 is a schematic view illustrating a connection structure of the resilient blade 390 and the first swing arm 330 of the juice extractor cutter 300 according to an alternative embodiment of the present invention, and fig. 12 is a schematic view illustrating a structure of the free end of the first swing arm 330 of fig. 11.

Referring to fig. 17 and 18, fig. 17 is a schematic structural view of a juice extractor cutter 400d provided according to an alternative embodiment of the present invention, and fig. 18 is a partially enlarged view II of fig. 17.

The difference between the juice extractor cutter 400d and the juice extractor cutter 100 is the different radial abduction mechanisms of the two.
In the juice extractor cutter 400d, the radially outward extending mechanism includes a slide bar 420d, a first rocker arm 430d, a second rocker arm 440d, a first link 450d, a second link 460d, and two lever sets 470d.

Referring to fig. 19 and 20, fig. 19 is a schematic view illustrating a structure of a juice extractor cutter 100c according to an alternative embodiment of the present invention, and fig. 20 is a schematic view illustrating a structure of the juice extractor cutter 100c of fig. 19 with a rotary member 140c removed. The difference between the juice extractor cutter 100c and the juice extractor cutter 100 is the different radial abduction mechanisms of the two.
The juice extractor cutter comprises a rotary member 140c, a resilient blade 170c, a radially outwardly extending mechanism and a stop 10. The radially outward extending mechanism includes a screw rod 110c, a first nut 120c, a second nut 130c, a rotating member 140c, a first rocker arm 150c, and a second rocker arm 160c. The radially outward extending mechanism is used to connect the elastic blade 170c to the rotating member 140c, and the radially outward extending mechanism is capable of driving the elastic blade 170c away from or toward the rotating member 140c in a radial direction of the rotating member 140c when operated.
The screw 110c includes a pivot section 113c, a first screw section 111c, and a second screw section 112c connected in sequence. The first thread segment 111c is left-handed, for screwing the first nut 120c. The second threaded section 112c is right-handed for screwing the second nut 130c. The pivot section 113c is adapted to mate with the swivel member 140c to form a rotatable shaft bore fit.
The second nut 130c has a substantially cylindrical outer shape and includes an outer circumferential surface, a screw hole, a hinge portion, and a guide portion. The thread rotation direction of the threaded hole is right-handed. The hinge portion is provided with a hole for enabling the hinge, the axial direction of which is perpendicular to the axis of the screw hole of the second nut 130c, and the axes of which do not intersect, i.e., form a spatial perpendicular relationship. The guide portion is a boss protruding from the surface of the second nut 130c in the radial direction, and the boss has a side surface (perpendicular to the end surface of the nut) parallel to the axial direction of the second nut 130c.
In this embodiment, the first nut 120c has substantially the same structure as the second nut 130c, except that the threads of the two nuts are opposite in direction, i.e., the threads of the first nut 120c are left-handed threads.
The first nut 120c is screwed to the first threaded section 111c of the screw 110c, and the second nut 130c is screwed to the second threaded section 112c of the screw 110 c.
The second swing arm 160c is rod-shaped, is provided with holes at both ends, and the axes of the two holes are parallel. The first rocker arm 150c has the same structure as the second rocker arm 160c, and the second rocker arm 160c has the same length as the first rocker arm 150 c.
One end of the second swing arm 160c is hinged to the second nut 130c, one end of the first rocker arm 150c is hinged to the first nut 120c. Meanwhile, the other end of the second swing arm 160c and the other end of the first swing arm 150c are hinged by a pin shaft.
When the screw 110c is relatively rotated with respect to the first nut 120c and the second nut 130c, the second nut 130c and the first nut 120c are moved toward or away from each other, thereby driving the angle between the second rocker arm 160c and the first rocker arm 150c to be smaller or larger, and at the same time, the end of the hinge between the first rocker arm 150c and the second rocker arm 160c can be far from or near the screw 110c.
The rotary member 140c has a cylindrical structure with one end opened and the other end provided with a shaft hole having a diameter smaller than the inner diameter of the cylinder, the shaft hole being coaxial with the cylindrical structure and having a diameter equal to the diameter of the pivot section 113c of the screw 110c. Rotating member 140c the cylinder wall is provided with with the runner parallel to its axis. The barrel inner diameter of the rotary member 140c is larger than the diameter of the second nut 130 c.
The pivot section 113c of the screw 110c is inserted into and rotatable in the shaft hole of the rotary member 140 c. The first thread section 111c, the second thread section 112c, and the first and second nuts 120c and 130c of the screw rod 110c are all located in the barrel of the rotary member 140c, and the guide portion 133c of the second nut 130c and the guide portion of the first nut 120c are located in the slide groove of the rotary member 140 c.
When the screw rod 110c rotates relative to the rotating member 140c through the pivot section 113c, the sidewall of the sliding groove 141c can act on the guide portion of the first nut 120c of the guide portion of the second nut 130c, and generate torque to the first nut 120c and the second nut 130c, thereby driving the first nut 120c and the second nut 130c to rotate relative to the screw rod 110c, and making the angle between the first rocker arm 150c and the second rocker arm 160c larger or smaller.
The elastic blade 170c is a long-strip-shaped blade having a thickness smaller than a width, and is elastically deformed when the blade receives a force in a thickness direction. One end of the elastic blade 170c is hinged to the bottom end of the rotating member 140 c.
The stopper 10 includes a ring body and a limiting portion 12, and in this embodiment, the limiting portion 12 has a cylindrical structure. The ring body has a central hole, and the limiting portion 12 protrudes radially from the ring body.
The stopper 10 is installed at one end of the rotating member 140c through a center hole thereof, and the stopper 10 is capable of sliding in the axial direction of the rotating member 140 c. The stopper 10 is mounted on the rotating member 140c, and the limiting portion 12 is located on a side of the elastic blade 170c facing away from the rotating member 140c, and a side of the end of the elastic blade 170c facing away from the rotating member 140c abuts against the limiting portion 12. When the elastic blade 170c is far away from the rotating member 140c, the limiting portion 12 can limit one end of the elastic blade 170c, but does not limit the sliding of the surface of the elastic blade 170c relative to the limiting portion 12, so that the end of the elastic blade 170c bends towards the center of the fruit, and excessive scraping of the peel portion at the fruit inserting opening by the elastic blade 170c can be avoided. The curvature center of the elastic blade 170c after bending is on the side of the elastic blade 170c facing the rotating member 140c, and the curved arc is closer to the shape of the fruit peel, so that the fruit pulp is scraped more fully.
In use, a larger distance is provided between the first nut 120c and the second nut 130c, and a larger angle is provided between the first rocker arm 150c and the second rocker arm 160c to push the elastic blade 170c to be close to the rotating member 140c, so that the whole juicer cutter has a smaller radial dimension. The juice extractor cutter is then inserted into a fruit such as orange, and the rotary member 140c is rotated, thereby causing the elastic blade 170c to perform a turning motion in the fruit, scraping the pulp. While the rotating member 140c is kept rotating, the screw rod 110c is rotated with respect to the rotating member 140c such that the distance between the first nut 120c and the second nut 130c becomes smaller, and the angle between the second rocker arm 160c and the first rocker arm 150c becomes smaller gradually, thereby driving the elastic blade 170c away from the rotating member 140c in the radial direction of the screw rod 110c, and further scraping the pulp. During the process that the elastic blade 170c is away from the rotating member 140c, both ends of the elastic blade 170c may be subjected to resistance by the inner wall of the pulp and/or the peel, so that the elastic blade 170c is bent in an arc shape. When the middle part of the elastic blade 170c touches the inner wall of the fruit peel, the whole arc of the elastic blade 170c can be attached to the arc of the inner wall of the fruit peel, so that the scraping of the pulp inside the whole fruit is completed.
